Title: A plant for narcotizing bacon hogs
IPC: A22B3/00
Filed: 1955-01-17
Abstract: 764,138. Narcotizing plant for bacon hogs. WERNBERG, N. E., and KRAGH, C. J. Jan. 17, 1955, No. 1378/55. Class 81(1) In a plant for narcotizing bacon hogs in which the hogs are carried into a pit containing a gas such as carbon dioxide, whereby they are narcotized directly before being stabbed, there is provided a number of movable hog boxes arranged successively in a closed circuit and moving compulsorily along a path of such form that the point where a box is located when the hog is removed it is located beside the place where the hogs enter the boxes. As shown in Figs. 1 and 2 the hogs are driven along a passage 7 through a door 8 of sector shaped crosssection and pivotable about a vertical hinge 10 and carrying. an operating arm 11 which when turned into the position indicated by a dotted line 11<SP>1</SP> admits the hog to the conveyer 12. Transverse fences consisting of vertical uprights 15 along the conveyer form boxes in which the hogs are carried into a covered pit 16 filled with a narcotizing gas such as carbon dioxide which is fed to the pit through pipings 64 leading from a storage tank 65 through a control box with cocks to the interior of the pit. The narcotized hog 27 lying in its box is carried up from the pit to a delivery point where an operator 30 attaches the hind legs of the hog 28 to a chain 29 which is then fastened to an inclined chain conveyer 31 on which the hog is hoisted on to a sliding rail 32 to be immediately stabbed in its neck so that the animal remains unconscious. In the plant shown in Fig. 5 the hog boxes 44 are mounted on two endless chains 45, one in front of and one behind the boxes, each of which chains passes around a pair of chain wheels 46, 47 moving stepwise in the direction of an arrow 48. When a hog 49 has entered a box 50 the box is lowered into a pit 51 filled with carbon dioxide and the hog is, in its narcotized state, carried up again to a delivery point 52 where an operator swings the one side wall 53 of the box down into its horizontal position, fastening the hind legs of the hog 54 to a chain and attaching same to an inclined conveyer 55 which carries the hog on to a sliding rail 56. In the plant shown in Fig. 6 the hog moves from the supply passage 57 along a bridge 58 displaceable in its longitudinal direction into a box 59 having a removable end wall 63 and spaced steel side members 60 on either side, the box being mounted as a gondola in a pair of arms 61 which arms may revolve stepwise moving 90 degrees at the time when the bridge 58 has been withdrawn free of the gondola. When the gondola is in the position denoted by 62 the narcotized hog is removed through the rear side wall the hog is attached to an inclining conveyer 55.

Abstract: 1,034,426. Capping bottles. BRAUEREIUND KELLEREIMASCHINENFABRIK MAGDEBURG VEB. Jan. 13, 1964, No. 1433/64. Heading B8T. A device for closing bottles with crown corks in which, in order to avoid breakage of bottles of abnormal height, after the closure operation has terminated an uncoupling of the transmission members, which comprise a closure plunger 1 and a bush 9 in which a closure case 8 is installed, is effected. During the downward motion in which an ejector 7a carried by a slide member 7 presses a crown cork on to a bottle 4 and the toothed edge is turned around the bottle neck by the closure case 8, the pressure of the bottle against a spring 15 has caused a surface 11 arranged on the slide member 7 to reach the level of slide blocks 10 which then slide inwards and uncouple themselves from grooves 12 so allowing the plunger 1 to continue its downward movement and the slide bush 9 to remain stationary. The plunger 1 is driven by a cam 2 through a roller 3. The blocks 10 have polygonal radial crosssection and possess curved outer surfaces which correspond to the groove 12 and the surface 11. When the closure plunger starts on its upward movement spring 15 presses the slide member downwardly so causing the bottle to be ejected from the apparatus.

Patent GB-855819-A (GB)
Title: Method of purifying nicotinic acid
Filed: 1958-01-16
Abstract: Crude nicotinic acid is heated to 200-270 DEG C., a current of carrier gas, inert to nicotinic acid and preheated to substantially the same temperature, is passed over it, and the entrained nicotinic acid is separated from the carrier gas. Suitable gases are air, nitrogen, hydrogen, carbon dioxide, or mixtures thereof.  The carrier gas containing entrained nicotinic acid may be passed into a cooling gas of substantially the same composition as the carrier gas, so precipitating at least part of the nicotinic acid; the mixture may then be passed to a solid-gas separation zone.  Alternatively, the carrier gas may be contacted at elevated temperature with a solvent which readily dissolves nicotinic acid at elevated temperatures but is a poor solvent at low temperatures, the solvent is then cooled, and the precipitated nicotinic acid separated therefrom; suitable solvents are water, methanol and butanol.  The two separation procedures may be carried out successively.

Abstract: 949,112. Endless conveyers. BAKER PERKINS HOLDINGS Ltd. Jan. 16, 1962 [Jan. 16, 1961], No. 1750/61. Heading B8A. The speed of a conveyer chain 1 over a length of which the links are collapsed into contact with one another in zig-zag or concertina fashion is less than that of the remainder in the ratio of the length when collapsed to that when extended. The slow-motion over a region 5 enables an operator to secure flat articles of laundry to cross bars (not shown) extending from the conveyer chain. Sprockets 2, 3 which carry the conveyer chain are connected by a chain drive 4, and a further chain 18 which is driven from a sprocket 19 on the shaft 20 of the main driving sprocket 2 drives a pair of sprockets 16, 17. The conveyer chain 1 leaving the driving sprocket 2 is under compression as it passes to the bottom of the region 5 and is therefore supported by guide surfaces 7, 8 which diverge to form a V-shaped space 12 within which the links of the chain can assume the collapsed configuration. The sprockets 16, 17 facilitate the collapsing of the links which pass upwardly between guides 6, 7.

Title: Improvements relating to hydraulic turbo couplings
IPC: F16D33/08
Filed: 1956-01-18
Abstract: 799,234. Hydraulic turbo couplings. SINCLAIR, H. Jan. 4, 1957 [Jan. 18, 1956], No. 1786/56. Class 69 (2). In a turbo coupling, the filling of which is variable to vary the slip and in which liquid is continuously drained from the working circuit and returned thereto through a cooler, means are provided to increase the cooling when the degree of filling of the working circuit decreases. Liquid is continually drained from the working circuit through restricted nozzles 21 into a reservoir 11 rotatable with the input shaft and containing a non-rotatable scoop tube 15 through which liquid is returned to the working circuit via a cooler. Tube 15 is radially displaceable to vary the thickness of the ring of oil in the reservoir and thus the filling of the working circuit. Valves 30 control exit ports from the working circuit. Each valve 30 comprises a plunger 39 connected to a bellows 34 which is loaded by a spring 36 and by the centrifugal pressure of the liquid in the reservoir which communicates with the exterior of the bellows through ducts 48, 47. When the scoop tube is fully extended the working circuit is full and only a thin residual ring of oil remains in the reservoir, and the plunger 39 closes its associated port. When the tube is retracted, the increased pressure on the bellows due to the increase in thickness of the liquid ring moves the plunger 39 inwards to open the associated port so as to increase circulation of liquid through the cooler. If desired the valves 30 may be arranged so as to never fully close, and the nozzles 21 can then be eliminated.
